Seeing all the awesome pictures of Norway lately my girlfriend and I have decided we need to go. We are planning on 10-14 days in the summer of 2014. Our preferences are for hiking and scenic outdoors, we are not a fan of big cities.

This trip will probably end up being our honeymoon so any other advice to make it go as smooth as possible would be greatly appreciated.

These are some of the most visited sites, so in good weather in the middle of the summer there are usually queues on the way up and down. Just something to keep in mind. Some of the hikes are also very physically demanding, so you have to be in good shape.

Preikestolen is very accessible and tourist- friendly. I've even seen Japanese people doing the "climb" in high heels. Not recommended though..
I would also recommend cycling the "rallarveg" which is a 1 or 2 day cycling trip with good gravel roads that ends up in flåm, an exceptionally beautiful small city located in a fjord. Great hotels and a local brewery. You can rent bikes. I've done it several times and my mind is blown every time by the beauty! the 1 day trip is mostly downhill as well :-)

I can't speak for the rest of the country, but on the west coast the weather is best mid-May to late June. Even that's a gamble, but if you want a chance at sunshine and clear skies, that's your best bet.

Buying food/drinks prepared by others (restaurants/cafés etc) is expensive everywhere, but it's downright insane anywhere someone gets a monopoly, like ferries, airports or museums. I know being careful with your money isn't going to be fun on your honeymoon, but we'll rob you blind if you're not careful. Bring your own alcohol or spend the trip sober.

As for transport, you might be best off renting a car. Public transport is unreliable outside cities and taxis are very expensive.

I realise my advice isn't very useful, but I'm not much for hiking myself so I can't give you much information on that. Hope you enjoy your trip!

That got me thinking - might it be cheaper to rent a car in Sweden than in Norway, and then simply drive across the border?

Like, fly into Stockholm, spend a day there, then pick up the (pre-booked!) car and go Oslo (don't stop) - Bergen - up north - back down through the flatlands of Sweden? I did a similar thing this summer, rented a car in Munich and spent two weeks in Italy. Saved me hundreds of Euros compared to Italian rentals.

10 days is short, though. Norway is a looooong country, and the fjords and mountains mean a lot of zig-zag driving and waiting for ferries.

Quite possibly. Depends where they want to start off and/or spend most of their time though. If they just want to hang out on the west coast or somewhere else far from a Swedish airport, it might not be worth the bother.

Finnmark (Most northern part) is absolutely worth visiting, consithering it has "North Cape" which is the northernmost point of Europe. Finnmark also has alot of the Sami people, which has an interesting culture.

If you are comfortable sleeping in tents, you can save a lot of money doing that when traveling outside the cities. It's free and legal on uncultivated land. I've met quite a few who combine tenting with couchsurfing.
